I agree somewhat, but nevermind Europe as a whole - I find it ironic that the Papacy in the form of the Papal States ended up becoming, quite in contrast, the final obstacle to Garibaldi's unification of Italy as late as the 19th century.
Indeed, this is one of the (many, many) bitter ironies of European history. The problem was that the Catholic Church obstinately refused to accept that its attempt to politically unify Europe under its rule had failed
, even centuries after it had become obvious to everyone else with half a brain. The Treaty of Westphalia is a clear example - the Pope denounced it loudly and vituperatively to anyone who would listen, but the statesmen of Europe simply ignored him, like the annoying buzzing of a fly in a conference chamber. From then on, the Papacy became increasingly irrelevant, until by the early to mid 19th century, it seemed to any objective observer that the Catholic Church was on a roller-coaster ride to oblivion. The fact that they managed to turn things around in the early 20th century is astonishing, quite frankly. Ridding themselves of the Papal States (or rather, having them taken from them at gunpoint) was a necessary first step in that revival.
